I've been hesitant to buy an electric grinder as I don't make espresso and the skerton works great but sometimes I'm in a rush and refuse to settle for a cup that's not quite what I like, so I took the handle off the grinder and used an electric drill, I just have to make sure it goes on straight and I get to "wobble", just wondering if anyone else has done this, or is it sacrilegious?

Dear Carlos,A while back I created a fitting for the shaft of my Hario mini to mate the five-sided shaft with my standard hex bit quick connect power screwdriver (B&D). I am sorry to say that the screwdriver was under-torqued by far to grind a pourover grind directly driving the grinder shaft. It seems the lever handle makes all the difference in mechanical advantage. I did not try it with an espresso setting, where the burrs would be experiencing less 'bite' into the bean and therefore may require less force, but I am not optimistic. A power drill would definitely work, but does not fit my requirement of a small, convenient set-up for me to pack in my luggage. If trying this at home, I would be careful to use a variable speed drill. A cheap one-speed drill may be more likely to damage the grinder.Buckley

It does work fine with my Porlex Tall mill, for both CCD/drip and espresso level grinds. But you need to be very careful tightening the chuck onto the 5 sided handle fitting (anyone know why all the Japanese grinders seem to use 5 sided shafts?) or the chuck will slip and wear the shaft's corner smooth. A specific fitting is better (and I believe they can be found on the internet) for the grinder.

Both the 9V and 18V cordless drills I have access to work fine for this, and are nicely controllable at slow speeds.
